How to use the electrolyte intake calculator
Prepare the values for this calculation
Sum logged sodium, potassium, and magnesium amounts without supplying intake targets. Use the formula below to check that it answers your question. Read the input units before transferring figures from a statement, measurement or dataset.
Enter and check each input
- Rows as sodium mg, potassium mg, magnesium mg: keep one record per line and preserve the column order shown in the example. Replace the example data with your own complete dataset.
The input table gives a complete example. Keep units and time periods consistent across related fields.
Calculate and resolve any input error
Choose Calculate after entering the values. Changes also update the answer after a short pause. If an error appears, follow its message, correct the field and calculate again. Reset restores the example values.
Interpret the answer
Check Logged sodium first. With the unchanged example inputs, it is 1,450 mg. Compare the additional metrics with the primary result; each has its own label and unit.
Compare and keep a useful result
The result diagram shows the inputs, method and output. A numeric chart is shown only when the calculation supports a meaningful numeric relationship.

Electrolyte Intake Calculator formula
Each electrolyte total is the sum of its entered amounts across rows.
Inputs and units
| Input | Format / range | Example |
|---|---|---|
| Rows as sodium mg, potassium mg, magnesium mg | One row per line | 500, 700, 80
350, 450, 60
600, 900, 100 |
Worked example
Using the example inputs above, the logged sodium is 1,450 mg.
- Logged sodium
- 1,450 mg
- Logged potassium
- 2,050 mg
- Logged magnesium
- 240 mg
- Rows logged
- 3
Results and assumptions
This is a log total only. It does not determine electrolyte requirements or diagnose deficiency/excess.
Fix an input or unexpected result
If your answer differs from the example, choose Reset and compare every field, including selected units and options. Check percentage versus decimal entry and whether values describe the same period. Round only the final displayed answer when reproducing the formula.
If a discrepancy remains, report the calculator issue with the page address, non-sensitive example inputs, actual result, expected result and a reference for your calculation.
